Syrenne, both of 1604 9th Ave. N., Saskatoon, Saskatchewan, Canada Filed Feb. 16, 1970, Ser. No. 11,752 Int. Cl. E03d 9/03 U.S. Cl. 4-225 3 Claims ABSTRACT F THE DISCLOSURE A screw-topped container having a. central side connection for attachment to and communication with the ilush pipe of a toilet and/ or a urinal; said central connection providing a sump in the container; said connection also r,projecting a baille into and across the llush pipe for water entrance to the container through the connection when the flushing operation occurs; a breather piping from the upper part of the container, through said connection and the baille, into the flush pipe to prevent an air lock and a vacuum in the container; a bag containing bactericide, water-immersed in said sump for protection from air deterioration and to enrich the water, for delivery to the ilush pipe in the draining of the container after said flushing.

This invention relates to means for sanitizing and deodorizing washroom appliances, such as toilets and urinals, when said appliances are provided with llush lixtures. It is well known that such appliances tend to stain and buildup deposits on the poreclain thereof when in use, and such are unsightly, offensive and usually germ-infested while their normal removal by mechanical means is impractical.

We are aware that chemical containers have been attached to the llush pipes of such appliances for release of their chemical into the flushing water, but such devices are usually mechanical and complicated and soon become defective. Others wastefully mix the chemical or wash it away before it can properly act, or it is too thinly mixed to do much good, and no means are provided to protect the chemical from air deterioration.

The principal object of the present invention is: to provide a container for quick attachment to the flush pipe of a washroom appliance, and such that said container will be tlooded when the appliance is flushed; and chemical in the container will mix with said flooding water for later mixed drainage to the appliance as a bactericide to remove stains and deposits from and deodorize the appliance.

A further object of the invention is: to provide a sump in the container for retention of water and immersion of solid bactericide therein, to protect the chemical from air Vdeterioration while the water will be enriched for controlled blending of the bactericide with the flooding water, in the flushing of the appliance.

A further object of the invention is: to provide a breather piping between the upper part of the container and the flush pipe, so the container can be water-fllled without air lock in the flushing of the appliance and said water can be drained to the sump level and out to the flush pipe without producing a vacuum in the container.

A still further object of the invention is: to construct the dispenser in a simple, economic and durable manner and Without mechanical means, for simplicity and economy of manufacture and operation, reasonable selling price, and many years of steady and satisfactory use.

With the above important objects in view, the invention consists essentially in the design, construction and arrangement of the various parts hereinafter more particularly Patented Nov. 30, 1971 ICC described, reference being had to the accompanying drawings wherein:

FIG. 1 is a side view of a toilet appliance and with the invention installed on the llush pipe.

FIG. 2 is an enlarged horizontal section taken on the line 2-2 of FIG. 1.

FIG. 3 is a vertical section taken on the line 3-3 of FIG. 2.

FIG. 4 is a perspective View of a modified clamping means for fastening the dispenser to the llush pipe.

In the drawings like characters of reference indicate corresponding parts in the several figures.

A toilet installation is shown in FIG. 1 and comprises a seated toilet 10 which is secured to the lloor 11 by bolts A llush pipe 13 connects the rear part of the toilet with a control valve 14 which is operated by a lever 15. And the valve is connected, through xtures 16, with a water supply pipe (not shown) in the Wall 17.

The dispenser itself is clearly shown in FIGS. 2 and 3 and comprises a bottle-shaped container 18 which is perferably formed from plastic and its upper end is normally closed by a threaded cap 19. A laterally extending connection pipe 20 projects centrally from the side of the container, is -molded integral with the container, and the outer end of this connection pipe is shaped in a semicircular vertical clamp portion 21. Outer lugs 22 on each side of the clamp portion receive corresponding lugs 23 on a semi-circular clamping plate 24 which completes the circle when saidvlugs are bolted together, as by bolts 25.

It will also be noted in FIG. 3 that the connection pipe 20, within the clamp portion 21, has its upper half cut away and the lower half projecting ahead to form a baffle 26, which will be later explained. A small piping 27 freely passes through the connection pipe 20, one end terminating in the upper part of the container 18, below the cap, and the other end passing through the baflle 26.

When the dispenser is to be attached to the flush pipe 13 of the appliance, a hole 28 is suitably cut through the wall of the ilush pipe. The clamping plate 24 is removed from the clamp portion 21 of the dispenser, and the baille 26 is passed through the hole 2S until said clamp portion seats around the wall of the flush pipe, it being understood that a suitable gasket 29 is inserted therebetween. The clamping plate 24 is then re-attached on the opposite side of the llush lpipe and the bolts 25 are tightened up.

From the above it wil be seen that the dispenser unit is now supported in a water-tight lluid connection with and on the ilush pipe with the lower end of the piping 27 in the ilush pipe, and a sump 30 i-s provided in the lower part of the container 18, below the connection pipe 20. The container cap 19 is then removed, a separate, loose bag 31 of stain-removing and deodorizing bactericide is dropped into the sump, which is then filled with water to protect the chemical from air deterioration while said water is enriched by the chemical. The cap 19 is then screwed back While we have shown and mentioned that the dispenser clamp is provided with lugs 22 and 23 for the tightening of said clamp to the llush pipe, it will be appreciated that other means may be used for this purpose, such as shown in FIG.. 4 and indicated in dotted outline in FIG. 3. In this latter arrangement, the lugs 22 and 23 are dispensed with while the flush pipe and the upper and lower parts of the clamp are each encircled by a broken ring 32 which can be tightened by an end-connecting bolt 33. This method holds the clamp very firmly, and is more streamlined. Accordingly, we do not wish to be limited to the exact details of the clamping arrangement.

In operation, when the appliance is ilushed from the valve 14 by operation of the lever 15, water pours down the ilush pipe 13 and past the baie 26. By observing FIG. 3 it will be seen that the bal-lle will divert a quantity of this water through the connection pipe 20 to fill the conainer 118. In this lling, air will pass from the upper part of the container down through the piping 27 to the flush pipe, and so prevent any air lock forming in the container. This sudden rush of water creates `a turmoil in the container which blends the enriched water of the sump therewith, and as the lushing water stops in the flush pipe, the excess blended water in the container drains back through the connection 20 to the ilush pipe and into the appliance so the chemical therein will remove all stains and deposits from the porcelain, while at the same time deodorizing the appliance. This draining of the container occurs down to the sump water level so the bag of bactericide is still immersed and protected from the air. As the Water level in the container recedes, air returns back up the piping 27 from the llush pipe to prevent any vacuum forming in the container. In other Words; the piping 27 forms a breathing connection or air vent for the container. When the bag of bactericide is used up, it is a simple matter to remove the cap 19 and insert another bagfull, as previously explained.

What We claim as our invention is:

1. A sanitary dispenser for a flush-operated washroom appliance, comprising: a container having a laterally extending connection pipe communicating with the flush pipe of said appliance, said connection pipe being central of the container to provide a sump in the lower part thereof, and means removably attaching said dispenser to said flush pipe; a baille extending from said connection pipe and projecting into and partially across said dlush pipe, for diversion of vilush water therefrom and into the container through said connection pipe, during the flushing operation; a separate, loose ba-g of bactericide water-immersed in said sump for protecting said bactericide against air deterioration, and to enrich the sump water with said bactericide; and said flush-diverted water adapted to blend with the sump water during the flushing operation, and said blending drain back through said connection pipe to the ush pipe, as said flushing operation slows down and stops.
